Apogee DDX 100% Digital Amplifier Technology Showcased at CES 2000

Apogee Technology's Direct Digital Amplification (DDX®) all-digital amplifier solution enables the world's first pure digital sound capabilities in these devices. This approach completely eliminates the need for digital to analog conversion, enabling digital audio sources to remain digital all the way from source to speakers.

As home theater enters the mainstream market, consumers are demanding products that combine ease-of-use with cutting-edge features -- ideally maintaining a pristine digital signal where possible. DDX amplifiers directly convert digital audio into power outputs suitable for driving loudspeakers at very high efficiency without the need for analog conversion. The result is 100% digital sound reproduction and reduced packaging compared to analog amplifiers that require large heat sinks and power supplies to overcome poor efficiency.

``The holy grail of the CE market is an integrated home theater system -- with DDX, a five channel amplifier can be made small enough to fit inside a DVD or almost any speaker enclosure. This gives manufactures the design flexibility and opportunity to develop easy-to-use integrated products that are pure, end-to-end digital,'' said David Meyers, Apogee's Director of Business Development.

About DDX

DDX consists of a controller that converts digital audio into Apogee's patented digital outputs and high-efficiency power switches. The design also solves analog noise problems and enables low-cost solutions through DDX controller integration into digital ICs.

Another major benefit of DDX is power efficiency -- up to 3X more efficient than analog amplifier designs. This reduces power supply and packaging costs, providing clear advantages for home theater and other audio applications.

Apogee is offering several levels of DDX product solutions to meet the needs of audio manufacturers. For audio or semiconductor companies desiring fully integrated solutions, Apogee is licensing its DDX Controller core. For medium power applications, Apogee has developed a DDX chip set solution that it expects to be available for customer sampling in 2Q'00. For high power applications, Apogee is introducing a board-level solution targeted for home and commercial powered speaker applications.
